So this was my first build an and purchased my parts of the course of 3 months to spread out the cost (even though it was a budget build).
I originally planned on getting the Sky Lake Core i3-6100, but then Kaby Lake was released and the Core i3-7100 was the same price. I checked the ASRock website to ensure my motherboard (B150 Pro 4v) would be compatible with Kaby Lake and sure enough it was with a BiOS update. So I went ahead and purchase the Kaby Lake b/c it was the same price.
Build day arrives and we have all our part. Build goes pretty quick (about 90 min) , since is our first build so took our time as we moved along.
Finally everything is connected we are ready to power on, fans light up and start spinning and wait for post, but the system begin to power cycle. This was my newb mistake not knowing that you can't get to the BiOS at all without a compatible processor. I'm sure this seem so simple but for a first time builder it not one of those things that anyone mentions.
The story has a happy ending, I got a Pentium G4400 Sky Lake the next day, plugged it in and flashed the BiOS. Then reinstall the Kaby Lake and we have POST window and access to UEFI.
Need to get an operating system installed and this baby will be fully functional. It was a really fun project for anyone who like to tinker and trouble shoot issues.
Note that I had to return the Arctic Freezer 7 CPU cooler that is in the pcitures b/c the fan didn't work. I actually didn't really like that CPU cooler looked so I'm going to buy the CRYORIG in my part list once I get my refund from Amazon.
